ABSTRACT:
In a method of analyzing and modifying a footprint depending on a specified number of texture elements touched by the footprint, in a graphics system providing the texture elements having a resolution, a dimension or a shape of the footprint is initially determined. On the basis of the specified number of texture elements and on the basis of the determined dimension or shape, the resolution of the texture elements associated with the footprint is specified. Then it is determined whether the graphics system provides texture elements having the specified resolution. If the graphics system provides texture elements having the specified resolution, the footprint is preserved. If the graphics system does not provide texture elements having the specified resolution, the texture elements which are provided by the graphics system and have a relevant resolution are selected, and those of the footprint are reduced such that the number of texture elements touched by the footprint having a reduced size is essentially equal to or smaller than the specified number.
